The Perfecseal plant at 9800 Bustleton Ave., Philadelphia, is being closed and its equipment being shipped to Wisconsin, according to Philly.com. 
About 200 union jobs will be lost.
The plant was opened about 60 years ago and acquired by Wisconsin-based Bemis Healthcare Packaging in 1986.
The Philly equipment will be used for an upgraded factory in the new right-to-work state. About 160 jobs will be created in Wisconsin.
Bemis, a publicly traded company with rising profits, has shut factories in Brazil and Mexico along with ones in Minnesota and Ohio to bring the work to the Badger State.
